The Tesla S I'm currently driving, pun intended, has autopilot. Utterly shit. It doesn't give cyclists as much room as it should. It won't register potholes and wants to stick rigidly to the centre of the lane. It's really quite stressful to use it even on motorways its answer to most things is to drop anchour and slam on the brakes. Certain overbridges on the M4 in bright sun cause it to see the shadow as something huge.
